Squirrel Nuts!

A squirrel may seem nutty when gathering nuts, but scientists have confirmed that their seemingly scatterbrained pursuit of them actually hides their sophisticated ability to categorize what they find. In the same way you may file your incoming emails by department or deadline, squirrels actually sort the nuts they find by size and type. The average squirrel can squirrel away as many as 10,000 nuts in a year.
